摘要:
A connection arrangement (1) comprising a pulling head (2) and an end part (4) of an electric cable (6), the electric cable comprising one or more electric conductor cores (16) surrounded by one or more external layers comprising an armour layer (18) of metal, the pulling head (2) comprising a metal sheath (8) with a first open end (10) adapted to receive said end part (4) of the electric cable, and a second end (12) provided with an attachment device (14) for attachment to a pulling device. The end part (4) of the electric cable (6) is connected to the pulling head (2) by means of a weld (34) connecting the armour layer (18) of the end part of the electric cable to the metal sheath (8) of the pulling head (2). A corresponding method is also described.
摘要:
Cable-termination device (1) having a housing (20) and an introduction opening (22) for a cable (6), in order to terminate the cable end (13) such that it is safe from contact. The housing (20) here comprises a termination cap (2) and a screw-connection unit (4) interacting therewith. The introduction opening (22) is provided in the screw-connection unit (4) for the purpose of accommodating at least one cable end (13). At least one latching device is provided for the purpose of latching the housing or the screw-connection unit (4) to the termination cap.
摘要:
A protective assembly for covering cable connections and splices and the like. The protective assembly comprises a rigid support structure (10) including a resin composition. The rigid support structure (10) has the shape of a hollow elongate tube in a central portion thereof and further includes a first reinforced end portion (18) opposite a second reinforced end portion. A rigid support structure (10) supports an elastic tube (58) capable of recovering substantially to its original dimensions after being stretched and released. The elastic tube (58) in the protective assembly is held in an expanded condition extending beyond the end of a rigid support structure placed inside the elastic tube. The rigid support structure is susceptible to breaking upon the application of a force beyond that exerted by the tube while in its expanded condition. Application of the force breaks the rigid support structure to permit recovery of the elastic tube.

Applicants have created an improved device and method for protecting from the elements wires which have a portion of their electrically insulative covering stripped off, such as spliced wires, and particularly stub-spliced wires. The device (100, 200) comprises (a) a dimensionally-recoverable tubing (102, 202), (b) a layer of sealant (104, 204) (which preferably also acts as an adhesive) applied to at least a portion of the interior surface of the tubing (106, 206), and (c) a cap or sheath (108, 208) into which at least a portion of the exposed wires are inserted, wherein at least a portion of the cap or sheath is positioned interior to the dimensionally-recoverable tubing. The cap or sheath includes a configured interior shape for holding the inserted wires, and is designed to permit the adhesive/sealant to flow around the inserted wires. The cap or sheath typically forms a closure at one end of the dimensionally-recoverable tubing or is positioned at or adjacent to a closure end of the tubing. At least the exterior, and preferably all of the cap or sheath is made of non-conductive material. The critical elements of the cap or sheath are that it includes a configured shape for holding the wires; that the configured shape permits a sealant/adhesive to reach the exposed portion of the wires and the juncture of the exposed portion with the portion having the electrically insulative covering, in a manner which is sufficient to provide a moisture-resistant sealing of the wires; and that the cap or sheath be constructed of a material which prevents wire poke through during the recovery of the dimensionally-recoverable tubing. A portion of the cap may act as the closure end of the device, having a shape which is easily grasped by automated handling equipment, with a configured shape for holding the wires extending from the cap portion which acts as the closure end.
摘要:
An umbilical cable assembly is created by a process which, in an embodiment, fits an abandonment cap onto an end of an electrically conductive cable as well as a polyethylene disc into which a set of connection pins have been pre-molded. The abandonment cap is injection molded onto the end of the electrically, conductive cable where a cylindrical volume of polyethylene is concurrently injection molded to the polyethylene disc. In certain embodiments some of the connection pins are connected to the umbilical's conductive power core.
摘要:
Eine Leitungsanordnung umfasst eine elektrische Leitung (100) mit einem Leiter (200), der von einem Mantel (300) umhüllt ist. Dabei weist die Leitung (100) ein Leitungsende (105), einen an das Leitungsende (105) angrenzenden ersten Längsabschnitt (110) und einen an den ersten Längsabschnitt (110) angrenzenden zweiten Längsabschnitt (120) auf. Im ersten Längsabschnitt (110) ist der Mantel (300) der Leitung (100) entfernt. Der erste Längsabschnitt (110) und der zweite Längsabschnitt (120) sind in einer Hülse (400) angeordnet. Dabei weist die Hülse (400) ein geschlossenes Ende auf. Die Hülse (400) ist mit dem ersten Längsabschnitt (110) der Leitung (100) vercrimpt.
